Study of microstrip for high gain

In high performance aircraft, spacecraft, satellite and missile application, where size, weight, cost, performance ease of installation, presently there are many other commercial applications, such as mobile radio and wireless communication. In this paper, a novel design technique for enhancing gain that improves the performance of a conventional microstrip patch antenna is proposed. This paper presents a novel wideband probe fed inverted multiple slot microstrip patch antenna. The design adopts contemporary techniques; probe feeding, inverted patch structure and stacked multiple slotted patch. The composite effect of integrating these techniques and by introducing the novel multiple shape patch, offer a low profile, broadband, high gain, and compact antenna gain of about 12.35 dBi and a fractional impedance bandwidth of 21.48%. The design is suitable for array applications especially for base station.
